Subject Re: What monitoring do you use/recommend?
Date Thu, 21 Apr 2011 17:13:30 GMT
   Hello Gautam,

   I recommend you to have a look at Hyperic HQ (1). I had very good
experiences with it, including a big french telco operator which has
been using it for more than three years nearly 100 Tomcat JVMs.
   VMWare/SpringSource is investing a lot on Hyperic HQ, the Open
Source / Community edition is used in production by very serious
system administrators, it is possible to monitor your custom metrics
(JMX + Hyperic XML based plugins).

   If you want much more sophisticated monitoring, I have been very
happy with AppDynamics. More expensive but very detailed and powerful
"business transactions oriented" monitoring.
